Microsoft Live Labs today announced Seadragon Mobile for iPhone. With the help of Seadragon you can now see giga-pixel images on your iPhone.
Seadragon Mobile brings the same smooth image browsing you get on the PC to the mobile platform. Get super-close in on a map or photo, with just a few pinches or taps of your finger. Browse an entire collection of photos from a single screen. You can browse Deep Zoom Images that you can create from your own pictures or your Photosynth collection (or anybody else's). Seadragon Mobile is available for free at the iTunes App Store.
This clearly shows Microsoft isn't ignoring the iPhone after all!
